Both of these beautifully kept homes are move-in ready. Most of the big-ticket items are already done! To name a few, there is an updated HVAC, newer windows and they have been fully remodeled. And if you’re not enjoying time indoors, the huge yard is simply waiting for you. There is a half an acre, fully fenced property, with an electric security gate. Here you are free to let your children run and play, while you lounge by the fire pit or exercise your green thumb in the small but established fruit tree orchard. If you’re an animal lover there is also a chicken hotel, just waiting for new residents and there is plenty of room to bring in a horse or two. This is the perfect house whether you’re into just watching your chickens mill about, walking your horses or enjoying the simple sounds of children playing. We invite you to lounge about in the private backyard, because this is the one.
